PIPE CONNECTION.

Specification of Letters Patent.

Patented July 5, 1910.

Application filed January 22, 1909. Serial No. 473,677.

To all whom it may concern:

Be it known that I, GEORGE R. BARD, a citizen of the United States, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Pipe Connections, of which tween them is made thoroughly fluid tight before any opening is made in the container walls.

To this end my invention consists in the novel construction, arrangement, and combination of parts herein shohvn and described, and more particularly pointed out in the claims.

In the accompanying drawings, wherein like or similar referencecharacters indicate like or corresponding parts; Figure 1 is a side elevation of my connection ,shown 'in operative position upon a main. Fig. 2 is a similar View showing a slightly modified form of my device. Fig. 3 is a view similar to Fig. 1 showing a longitudinal sectionof the connection taken substantially on line 3-3 of Fig. 4. Fig. 4 is a section taken substantially on line ei-.l: of Fig. Fig. 5 is a partial section taken substantially on line 55 of Fig.4., showing the preferred form of face adapted to cooperate with the container wall, to hold the packing material in position. r

In the form shown in the drawings, my connection consists of the tubular connection 1, having a face formed at one end adapted to cohperate with the surface of a steam, gas, water or other main or container 2, and with means at its opposite ends for conveniently attachinga valve, pipe, or the like to the connection and with means for rigidly holding my connection in position upon themain or container. Y

Inthe form shown, a part 3 at the inner edge of the face of my connection is formed to substantially fit the surface of the container with which it ,is to coiiperate. The

= remainder of the face is suitably spaced from the surface of the retainer to receive a ring 1 of plastic, malleable or other. suitable packing to form a perfectly tight joint between the connection and container.

The part 3 is provided to accurately control the position of the packing and prevent the probability of any portion of the packing extending into the interior of the connection. This part also operates as a wall so that the packing may be calked or forced inward against its outer surface to compress the packing and force thesame into any depressions or crevices to form a satisfactory joint. Inthe form shown also a portion 5 atthe outer margin of the face of my connection is spaced from the surface of the ci'mtainer slightly less than the desired thickness of the packing and the part of the facehetween the parts 3 and 5 is concave or curved inward thus forming an annular chamber adapted to securely hold the packing in position and preventing the escape of the packing either inward or outward when it is in position. The chamber thus formed is of an extremely desirable shape to receive the packing into which it may be forcedto form the most satisfactory and secure joint.

Any suitable means may be provided for attaching a valve, pipe, or the like to the opposite side or end of my connection. In the form shown a nipple or neck 6 or the usual or any preferred form is provided upon my device to which a valve or pipe may be at ta-oiled by means of suitable packing in the usual or any desired manner. Any suitable means may be provided for attaching my connect-ion to the main. As shown, a pair of lugs or cars 7'-7 are provided upon opposite sides the member 1 each of which is provided with a slot 8 adapted to receive a bolt 9 or equivalent means for securing the connection in position.

In the form shown inFigs. 1 and 3, the bolt 9 is threaded at one end and its opposite end is flat and provided with a hook 11 or other suitable means adapted to interlock with a corresponding part upon the bolt S at "the opposite side of the main to operate as a strap to rigidly bind my connection in position upon the main.

The form shown in Fig. 2, is particularly adapted Where my COllllifCi-lnll is to be applied to a comparatively large main where it is impracticable to extend the ears ''(7' snfiiciently to employ the form of clamp roe ' shownin Figs. 1 and 3. In this form the i extremities of the band 12.

bands 12-42 are bent outward at their ends lti adjacent the connection and are each pro-' vided with a suitable opening to receive a bolt 14 to attach the-bands to the connection. In this case the ears 1515 are formed at an angle. corresponding with the angle of the "In operation my connection is placed in the desired position upon the main, the

bands 9 or 12 are passed around the container and connected after which the bolts are tightened to clamp the connection securely 1n place. When this is accomplished melted lead or other suitable material is in-' troduced in the usual or any desired manner -1nto the'space between the connection and the surface'of the container. The packing may now be calked' or forced inward at the periphery ofthe ring of packing to expand the same against the face of th s connection v and the surface of the main to receive a thoroughly fluid tight joint. When thus arranged a-suitable valve (not shown) may be attached to my connection and an opening formed in the wall of the main correspond- 'ing to the opening through the connection.

Having thus described my improvement, it is obvious that various immaterial modifications may be made in my device without departing from the spirit "of iny invention, hence I do not wish to be understood as limiting myself to the exact form and construction shown.

What I claim as new, and desire to secure By Letters Patent is a 1 In a structure of the character described, the cpmbination with a main conduit, of a branch conduit comprising a tubular head and a conducting pipe leadingtherefrom, the lowerface of said head being transversely recessed upon the arc of a circle to. cause the lower end of said headlto fit snugly upon the periphery of the main co'nduit and the lower edge of said branch conduit being circumferentially recessed such 3 manner that the outer wall of said recess exthe inner wall thereof, the inner wall of said recess contacting with the main conduit and the lower edge of the outer wall of said recess being sli 'htly spaced from said main conduit whereby packing may be forced into. said recess after the branch conduit is in position with relation to the main conduit, and means for forcing said branch conduit tightly into contact with the main conduit.

2. In a structure of the character described, the combination with main conduit, of abranch conduit comprising a tubular head and a conducting pipe leading therefrom, the-lower face of said head being transversely recessed upon the arc of a circle to cause the lower end of said-head to fit snugly upon the peri hery of the main conduit and the lower ,e ge of said branch conduit being circumferentially recessed in such manner that the outer wall of said recess extends downwardly considerably farther than the inner wall thereof, the inner wall of said recess contacting with the main conduit and the lower edge of the outer wall of ,said recess being sliqhtly spaced from said main'conduit where )y packing may be forced into said recess after the branch conduit is in position with relation to the main conduit, means for forcing said branch conduit tightly into contact with the main conduit, said means comprisin a two part strap having interengaging em s at their lower portio s and out-turned ears at the upper portions, and fastening devices which pass through said out-turned ears and through extensions of said head.

n In testimony whereof, I have hereunto signed my name in the presence of twosubscribing witnesses.

GEORGE R. BARD.
